  1. Does anyone have a Geekbench result yet on the iMac 2019 with the 9th gen 3.7Ghz Core I5 processor? I am very curious how it performs comparing to the 3.2Ghz I7 in the MacMini and the I9 in the iMac....

Oh nice, thx. I didn't know you could search that way...

Can anybody explain why there are so big differences between the entries?

From the few posts I seen it looks like the New iMac i9 is 13% faster in multicore and 6% faster in single core to the MM i7.

I am getting these calculations from a poster Samppaa

Score for the processor: Single core 6256, Multi-Core 30582

vs my i7 Geek Bench 4 runs about 5900's and 26,700's

It will be interesting to see some i5 results.

It can be a few things, if the iMac is still indexing from new, spotlight, photos etc. It can be heat related if you run the test over and over things typically slow down from my experience. The CPU best score comes from a cool machine with nothing running in the background. At least my experience shows this.

Is it possible that RAM amount has an impact?
In theory the benchmark should evaluate the processor only, but I see higher results for 32/64GB than for 8GB iMacs.

Yes I forgot about that scenario. I did see increased scores on GB3 at the time with my 2015 iMac going from 8 to 16 to 32. 8 to 16 was the biggest jump if I remember correctly.

Many of the i9s with 32GB of RAM were more like 33,000-35,000. Wonder if those people also let them settle down first? Will be testing mine tonight after it’s done with all the startup stuff. I was hoping for a bit higher. It’s funny, someone on here had been posting some iMac18,3 results as the new iMac and tricked a lot of us. I remember thinking it was on 19 but there were so many unlabeled 18s in there that I just went with it. They had scores that averaged more in the 35,000-38,000 range and had me excited but I guess those are just modified PCs with better cooling. Wondering if I should have gotten a refurbished iMac Pro instead…

Checking the latest tables, the i9 seems to be like a 60% better on MC.

SC is only around 8% ahead.

That seems a massive difference for 2 additional cores.

Don’t forget about the i9’s hyperthreading so it can handle 16 threads over the i5’s 6 threads. I believe geekbench includes HT, not just physical cores.

but even if the score includes HT, it's still a valid score as as much as you don't get the aditional cores, you do get the performance boots
